'This' inventionfrelates to a condensing plantV for vehicles in which cooling water.,

trickles over the'tubes of a surface condenser while, at the same time, cooling air plays over them, and inwhicli a water-jet ejectoris provided .for extracting the air vfrom the 25 partly Va vlongitudinal section of a booster` condenser. The invention consists in causing the .water whichV operates the ejector, andgas such circulating "cooling waterfis used, to trickle over theV condenserdirectly after it leaves the ejector. Thus,.in a manf ner known perse, lthe invention renders.

a single pump sutlicient for circulating the cooling Water for theV condenser and the waterl for working. the Vwater-jet ejector, while, at the same time, it secures vthe ad- Lvantage that such circulating pump has only* to produce a comparatively small head of water, as large quantites/of water are available for the ejector.

The accompanying drawing shows diagrammatically, byway of example, two con- Astructional forms of the invention.

by a pipe '13 tothe 'ejector 12.v The waterv i which-works this ejector trickles, afterV it leaves the pressure pipe 14;, directly over s the surfacecondenser 6, being there brought into intimate contact with air drawn through between the condenser tubes,.from the bottom upwards, by exhaust fans 15,'and thus itis subjected to astrong cooling action by reason of the evaporation which takes place. The water which triclles over the condenser' 6 collects in altanl .10,fwlienceit is again drawn by the pump V9 to repeat its cycle.

Instead of using in the manner shown in Fig. 1 all the water supplied by the pump 9 for operating the ejector 12, only aportion of thiswater may be sent through the said ejector. Fig-2 shows such an arrangement in which only a portion of .the water sup- Y.
